Continuous stationery assemblies

ABSTRACT

A series-connected business form is adapted to be fed through the printing means of a business machine and includes a continuous pair of superimposed outer webs each having feed bands including rows of spaced superimposed feed holes extending along opposite marginal edges thereof for engagement with the feed means of the business machine so that the form may be thereby advanced into and past the printing means. At least one intermediate web is disposed between the outer webs with transfer material lying on opposite sides of such intermediate web, and the intermediate web is secured to .[.only.]. one of the outer webs. The webs are divided by transverse lines of weakening so that the form is separable into individual units, and the one web and its attached intermediate web are removable from the remainder of each unit inwardly of the feed bands, so that, upon the printing of a number of such units, the next to the last of such units so printed may be separated along the transverse lines of weakening whereafter the one web and its intermediate web secured thereto of the last of such units may be separated from the other of such webs to leave such other web of the last unit and its connected feed bands available as a drive web for initiating the feed of the remaining units to be printed.

This application is a continuation-in-part of U.S. application Ser. No. 727,518, filed Sept. 28, .[.1978.]. .Iadd.1976.Iaddend..

Many kinds of Continuous Stationery Assemblies have been proposed for feeding to the print units of what are referred to as mini-computers. These have included plain paper webs--perhaps bearing blocks of transverse lines spaced apart by distances of 1/6". These webs are made up into packs, the individual webs being interleaved with one time carbon webs. More sophisticated continuous stationery assemblies have also been used and these include for example the continuous manifold form assemblies described in British patent specification No. 919,496 and the Business Forms Stationery as described in British patent specification No. 1,376,447. All these assemblies include marginal feed apertures. Many of the continuous stationery assemblies are used with office computers and terminal printers and are used for relatively short runs. When such assemblies are positioned in the print unit of the computer the marginal feed apertures at opposite sides of the continuous stationery assembly are engaged on the feed pins of a pair of feed pin tractors at the outfeed side of the print unit. When it is required to feed the stationery assembly the tractors are driven and the stationery is fed. The tractors have of necessity to be positioned several inches above the printing position so that each time a fresh continuous stationery assembly is loaded into the front unit, one set (one form length) at the loading end of the assembly is lost.

Although this constitutes a loss each time a new pack of forms is loaded into the print unit greater losses are incurred when it is necessary to print a few form lengths at a time and especially if a single form length only is to be printed because at each printing operation a partly used pack is inserted and this entails losing one form length at each reloading.

A continuous form assembly is disclosed in the aforementioned U.S. Ser. No. 727,518 as comprising a plurality of continuous stationery webs with the last web and at least one other web containing lines of marginal feed apertures, the webs being joined together adjacent their margins wherein the webs intermediate the first and last webs have a width less than the width of the first and last webs, the intermediate webs being joined together and the first web of the assembly having a line of longitudinal perforations substantially in line with the edges of the intermediate webs so that the intermediate webs can be detached from the last web.

It is an object of the present member to provide an improved continuous stationery assembly.

It is another object of the present invention to provide an improved continuous stationery assembly in which it is not necessary to lose a form length each time a web of continuous stationery assembly is fed into the print unit or the like.

According to the present invention a continuous stationery assembly comprises a front web, a back web and at least one intermediate web with the webs being joined at one marginal edge, a line of longitudinal tear off perforations being provided in at least the front web to separate the back web from the other webs.

A continuous stationery assembly in accordance with the present invention will now be described by way of examples with reference to the accompanying drawings wherein:

FIG. 1 is a diagrammatic plan view, partly cut away, of a continuous stationery assembly according to the invention;

FIG. 2 is a cross-sectional view of the assembly taken substantially along line 2--2 of FIG. 1, with the distances between the parts of the assembly exaggerated for the sake of clarity;

FIG. 3 is a diagrammatic plan view, partly cut away, of a continuous stationery assembly according to another embodiment of the invention; and

FIG. 4 is a sectional view of the assembly taken substantially along line 4--4 of FIG. 3.

Referring to FIGS. 1 and 2 of the drawings there is shown a continuous stationery assembly comprising a back web 1 and a front web 2 having a width of the same as that of the back web 1 and in registry therewith.

A plurality of intermediate record webs 3 are located between back web 1 and front web 2. The lefthand edge of these intermediate webs 3 (as viewed in FIG. 1) is in registry with the lefthand edges of front web 2 and of back web 1. Each of the intermediate webs 3 extends across and between webs 1 and 2 to a position short of the righthand edge of back web 1 and of front web 2. The lefthand side of each of the record webs 1, 2 and 3 has a line of longitudinal marginal feed apertures 4, the apertures in each web being in registry with corresponding feed apertures 4 in the other webs. A line of longitudinal feed apertures 4a is provided in the righthand side of back web 1 and of front web 2 in registry with each other. The righthand sides of the intermediate webs do not extend as far as the line of apertures 4a. Transfer webs 5 (for example of carbon paper) are interleaved with record webs 1, 2 and 3 to provide means for providing on record webs 1 and 3 a copy of the data, etc. written on front web 2. Transfer webs 5 are secured to webs 1 and 3 next above them by a respective longitudinal line of adhesive 6, and these transfer webs 5 are secured to intermediate webs 3 next beneath them by a respective longitudinal line of adhesive 7. The lowermost of the transfer webs .[.4.]. .Iadd.5 .Iaddend.is not, however, secured to back web 1 by such a line of adhesive.

A longitudinal line of adhesive 8 is provided a short distance within the righthand side line (FIGS. 1 and 2) of marginal feed apertures .[.3.]. .Iadd.4a .Iaddend.to secure the righthand side of front web 2 and the righthand side of back web 1 together, and a longitudinal line 8a of tear off perforations is provided at one side of front web 2 just within the line of adhesive 8. This line of tear off perforations 8a is aligned with the righthand edge of intermediate record webs 3. Further lines of adhesive 9 are provided, one each such line being provided between front web 2 and the uppermost of intermediate webs 3, between each pair of adjacent intermediate webs 3, and between the lowermost of intermediate webs and back web 1. These lines of adhesive are each located at the lefthand side (FIGS. 1 and 2) of each web just within line 4 of feed apertures. A longitudinal line of tear off feed perforations 10 is provided just within lines of adhesive 9 in front web 2 and in each of intermediate webs 3 but not in back web 1. These lines of perforations when torn off separate the back web with the stub on the lefthand side from the record webs 3 and transfer webs 5.

A further set of lines 11 of longitudinal tear off perforations are provided in each of front web 2 and intermediate webs 3, but not in back web 1, just within the set of lines of adhesive 7 joining the transfer webs to the adjacent record webs. These lines 11 of perforations serve as snap out perforations to separate the part of the carbon webs from part of the record webs after the webs have been processed.

Each of back web 1, front web 2 and intermediate webs 3 are divided into form lengths by lines of transverse tear off perforations 12.

Preferably lines of inclined slits .Iadd.14 .Iaddend.are formed in transfer webs 5 between respective lines of adhesive 6 and 7. These inclined slits are more fully described in British Patent Specification No. 919,496.

A continuous stationery assembly as described is loaded into a mini-computer and data is printed on a form length assembly as is required. The form length is then fed by tractors of the mini-computer to the outfeed side of these tractors whereupon the typed form length of front web 2 of the assembly together with a corresponding form length of intermediate webs 3 is detached from the back web 1 by breaking the line of tear-off perforations 8a and 10. Thereby a form length set is detached. This form length set is in the form of a snap out set. The stub portion and the transfer webs can be separated from the record webs by tearing across the lines of snap-out perforations 11. The back web together with the marginal parts of the front web remain and serve as a drive sheet for feeding the remaining part of the web through the mini-computer. The stationery assembly can be removed from the mini-computer and when the assembly is reloaded the leading part of the assembly constitutes a means for being located on the feed pins of the tractors whereby the whole assembly can be fed through the mini-computer without losing the leading form length when reloading. It will be apparent that the back web of the assembly constitutes a file copy web.

A modified continuous stationery assembly is shown in FIGS. 3 and 4. This is similar to the assembly shown in FIGS. 1 and 2 and includes a back web 1, front web 2 with intermediate webs 3 with transfer webs 5. The assembly includes feed apertures 4, 4a and lines of adhesive joining the intermediate webs to the front and back webs. The transfer webs are secured to the front web and the intermediate web above them (but not to the back web) by respective lines 6 of adhesive between the under face of the front web or intermediate webs and the front face of the transfer webs. In this assembly there are no lines of inclined slits nor lines of adhesive securing the rear face of the transfer webs to the front face of the intermediate webs.
